Needed: 3-bar DFI tune
I changed my MAP to a 3-bar from a 2-bar. If you have a DFI Gen-VII, I would appreciate being able to view your VE table or tune for that matter. I have a good DFI Gen-VII, 2-bar tune, for a 394LT4 w/AFR-220 heads, 224-236 114lsa cam, making 16 PSI, that I could share.

You should be able to take your current mapping and modify it for a 3 bar setup.
It is basically a bunch of copy-paste steps, actually typing. If you load your normal profile and then change the MAP sensor type it should change the axis values in the VE and timing tables. You then need to adjust the values accordingly.
You can scale the axis values too and that will keep the typing to a minimum. so you use the first 8 lines for vaccume in the 2 bar, swap to a 3 bar and then change the axis values to match those you had in the 2 bar setup so the first 8 lines correspond to vaccume readings.
this gives you less resolution in the boost section, but keeps the driveability tune that you already have in your car.
I would like to take a look at your tune none the less if you don't mind sharing. If you could email it to me that would be cool, bmckevett@yahoo.com.

Have you had a chance to look at the tune I sent you? What are your thoughts? If you dont mind, would appreciate seeing a copy of your tune, too.
Thanks,
Chris
